high MPR rating of 2500, your AC filter will capture many microparticles – such as pet dander, smoke, bacteria and viruses – letting cleaner air flow through. This air filter captures up to 90% of airborne virus particles (1) to help make your air cleaner. Your filter will also capture...
This new high performance filter is 97% effective at attracting and capturing large airborne allergena like pollen, mold spores and dust mites. This carries 3M's microparticle rating of 1550 (approximately equivalent to MERV 11 rating). Media is electrostatically charged. This filter should be ...
Pressure drop is a measure of the filter's ability to allow air flow through the filter media and is also an indicator of filter life. A lower pressure drop number means better air flow. Pressure drop numbers for Filtrete filters fall within acceptable ranges.Because of their high efficiency,...
This wider spacing reduces resistance, allowing higher air flow through the filter. It is the high pressure drop that makes quality HEPA air purifiers so loud. So the lower pressure using an electret filter allows 3M FAP03-RS to run on higher settings quietly. Electricity costs are also re...
